Opening SubVI Front Panels During Execution

A single front panel sometimes is too restrictive to present numerous options or displays. To solve this problem, organize VIs so the top-most VI presents high-level options, and subVIs present related options.

Tip You also can use tab controls to make the front panel more usable.

When LabVIEW calls a subVI, ordinarily the subVI runs without opening its front panel. If you want a single instance of the subVI to open its front panel when called, use the SubVI Node Setup dialog box.

If you want every instance of the subVI to open its front panel when called, use the VI Properties dialog box.

Single Instance

Complete the following steps to have a single instance of a subVI front panel open when called.
